Mathematics
1 answer:
Nina [5.8K]3 years ago
3 0

Answer:

Step-by-step explanation:

(a) The appropriate formula is C = 2πr.  Here r = 14 cm, so

C = 2π)14 cm = 28π cm, or (if we take π to be 22/7), C = 88 cm²

(b) We use the same circumference formula:   C = 2πr  and solve it for r before inserting numeric values:

        C                                                 132 m               7(132 m)

r = --------         and in this case,   r = ------------------- = ------------- = 21 m

      2π                                                [ 2 * (22/7) ]            44

KIM [24]

Answer:

1

Step-by-step explanation:

To solve this, first, take 22 minutes and divide it by 60 minutes, which is the number of minutes in an hour. Then, add two to the value, and multiply it by six square meters per hour, which is the rate that David can paint the wall. From there, you get 14.2 square meters which he painted in 2 hours and 22 minutes. Divide 14.2 square meters by the length of 11 meters to get 1.290 meters. Since they asked you to round to the nearest meter, you get 1 meter.
